CROSS-REFERENCE TO RELATED APPLICATION

This application is a continuation of U.S. patent application Ser. No. 17/014,629, filed Sep. 8, 2020, which is based upon and claims the benefit of priority from Japanese Patent Application No. 2019-164499, filed Sep. 10, 2019, the entire contents of which are incorporated herein by reference.

FIELD

Embodiments described herein relate generally to a maintenance support device, a maintenance support method, and a non-transitory computer readable medium.

BACKGROUND

When an error occurs in an image forming apparatus such as an MFP (Multifunction Printer), image formation may be interrupted and a business operation may be stopped. To prevent such an error, a maintenance worker may routinely check the condition of the image forming apparatus on a regular schedule and do maintenance work as necessary.

However, whether a potential error can be prevented depends in part on the skill level of the maintenance worker performing the maintenance check. For this reason, online support systems have been developed to allow relatively unskilled maintenance workers to acquire necessary information and do appropriate maintenance work depending on the condition of an image forming apparatus even without extensive experience and/or high aptitude. Such support information is prepared based on a maintenance record that have been reported by a skilled maintenance worker.

In such online support systems, an operator needs to review maintenance reports reported by maintenance workers and determine which of the reports that are useful and should be by unskilled maintenance workers as a reference. However, since there are many maintenance reports reported by skilled and unskilled maintenance workers, it can be difficult for the operator to identify an appropriate maintenance record in a timely manner.

The regions 611 to 614 are regions indicating the details of the maintenance work that has been performed to solve the failure of the image forming device 100. The region 611 indicates the solution type that was performed to solve or try to solve the reported failure of the image forming device 100. In this context, the “solution” field (region 611) indicates a general explanation of the solution type of the maintenance work that has been performed. The “solution” field is filled by the maintenance worker who has performed the maintenance work. The depicted region 611 indicates “user explanation” as an example of a solution type that has been performed. This depicted example indicates that a “user explanation” has been performed as the maintenance work. In this context, “user explanation” means that the maintenance worker has attempted to resolve the failure by providing instructions verbally to the user on how to solve the failure of the image forming device 100. As in the depicted example of FIG. 5 , the solution type may be input via selection from a pull-down menu. Alternatively, the solution type may be input as text. As the solution types, for example, “part replacement”, “setting”, “adjustment⋅or cleaning”, or “user environment maintenance” may be selectable. The “part replacement” solution type indicates maintenance work required replacing a part of the image forming device 100. The “setting” solution type indicates maintenance work required changing a setting of the image forming device 100. The “adjustment⋅or cleaning” solution type indicates maintenance work required physically adjusting equipment inside the image forming device 100 or cleaning the inside the image forming device 100. The “user environment maintenance” solution type indicates the performed maintenance work related to changes or adjustments of a user environment in which the image forming device 100 is used, such as a network environment.

The region 612 indicates a large category (broad category) of an information source that has been referred to by the maintenance worker to perform the maintenance work on the image forming device 100. The large category is input by the maintenance worker. The large category may be selected via a pull-down menu. For example, the large category may be “manual”, “service materials” or “service social networking service (SNS),” which is provided for maintenance workers. In this context, “service materials” refer to various materials that disclose possible solutions to solve failures of the image forming device 100, such as notices or memos posted to an internal digital bulletin board provided for maintenance workers. In this context, the “service SNS” is a web service used by maintenance workers to exchange information. The service SNS is used to share information such as a repair solution of the image forming device 100.

The region 613 indicates a middle category (sub-category of a broad category) of the information source indicated by the large category. For example, when the large category is a “manual”, the middle category (sub-category) is a “user manual” or a “service manual”. The middle category is input by the maintenance worker. The middle category may be selected via a pull-down menu.

The region 614 indicates a small category (sub-category of the middle category) indicating specifically which portion of the information source specified by the broader categories was referred to by the maintenance person for performing the maintenance work. For example, when the middle category indicates a “user manual” or a “service manual,” the small category may be, for example, a particular chapter number or section number. The small category is input by the maintenance worker. The small category may be selected via a pull-down menu. The small category may not always be available for selection/input depending on the particular selected middle category.

According to the regions 612 to 614, in the first row of solution details, “manual” is input as the large category, “user manual” is input as the middle category, and “10-37” is input as the small category. This example indicates that the maintenance worker has provided a solution to the user based at least in part on the explanation found in chapter 10, section 37 of the user manual.

According to the regions 612 to 614, in the second row of the solution details, “manual” is input as the large category, “service manual” is input as the middle category, and “36-29” is input as the small category. Thus, this example indicates that the maintenance worker has provided a solution based at least in part on the information explained by chapter 36, section 29 of the service manual.

According to the regions 612 to 614, in the third row of the solution details, “service materials” is input as the large category, and “SV0342” is input as the middle category. Thus, this example indicates that the maintenance worker has provided a solution based at least in part on the information explained in to the particular one of the various service materials labeled/titled/referenced as “SV0342”.

The region 615 indicates images of reference buttons for retrieving the information sources as specified by the large category, the middle category, and the small category. In response to a selection of one of the reference buttons, a request is issued for retrieving the corresponding information source from the maintenance support device 400. For example, when a maintenance worker is checking the work result information 600 via the screen shown in FIG. 5 using the terminal device 300, when the worker makes a selection of the reference image in the first row of the solution details, the processor 304 of the terminal device 300 issues a request for data of a user manual specified by “manual” as the large category, “user manual” as the middle category, and “10-37” as the small category, to the maintenance support device 400. Upon receipt of the corresponding manual data from the maintenance support device 400, the processor 304 controls the output unit 306 to output the user manual information. The maintenance worker can perform maintenance work on the basis of the user manual which has been output via the output unit 306. In general, any information may be freely input into the regions 611 to 614 as solution details for aiding future maintenance work concerning similar failures.

According to depicted the regions 712 to 714, in the first row of the solution details, “manual” is input as the large category, “user manual” is input as the middle category, and “45-25” is input as the small category. This example indicates that the maintenance worker has referred to chapter 45, section 25 of the user manual for the performing the part replacement.

According to the depicted regions 712 to 714, in the second row of the solution details, “no materials” is input as the large category, “parts” is input as the middle category, and “Part No. 9876” is input as the small category. The information input in the small category indicates a part number. This example indicates that the maintenance worker has replaced a part of the image forming device 100 which is specified as Part No. 9876.

The region 715 has images of reference buttons for retrieving information sources as specified by the large category, the middle category, and/or the small category. In response to a selection of a reference button, a request is issued for retrieving the corresponding information source from the maintenance support device 400. For example, a maintenance worker reviewing the work result information 700 via the screen shown in FIG. 6 using the terminal device 300, in response to a selection of the reference image (button) in the first row of the solution details, the processor 304 of the terminal device 300 issues a request for data of a user manual specified by “manual” as the large category, “user manual” as the middle category, and “45-25” as the small category, to the maintenance support device 400. Upon receipt of the corresponding manual data from the maintenance support device 400, the processor 304 controls the output unit 406 to output the received user manual. The maintenance worker can perform maintenance work on the basis of the user manual information which has been output via the output unit 306. In general, any information may be input into the regions 711 to 714 for explaining the provided solution(s).

The work result information shown in FIGS. 5 and 6 is not limited to the above-described example. For example, the work result information may indicate a work time that has been scheduled for completing maintenance work. In addition, the work result information may indicate costs required for part replacement and/or the service fees for the replacement of the part. Furthermore, the work result information may include specific work details that have been input by a maintenance worker via the input unit 305 in free format (e.g., a “notes” field or the like) as additional information related to the work result. The processor 304 records the additional information as a part of the work result information.

FIG. 7 is a diagram showing a work information table according to an embodiment. The data of the work information table is stored in the storage device 403. The work information table includes a plurality of records each storing the work result information, as described above. Thus, each record corresponds to the work result information including the work report number, the date of work, the name of the maintenance worker, the device ID, the failure, the error code, a flag indicating whether the failure has been solved, the solution type, the large category, the middle category, and the small category. Additionally, each record includes a device type, which is an identifier for identifying the device type of the image forming device 100 and this can be associated with a device ID. Thus, when new work result information is generated, the processor 404 stores it in a new record of the work information table, and identifies and stores the device type corresponding to the device ID.

FIG. 8 is a flowchart of a process of generating the work information according to an embodiment. In this example, the output unit 306 of the terminal device 300 is a display device such as a display screen.

Initially, when a user of the image forming device 100 makes a call to a call center, a call center worker who responds the call operates his or her own terminal device to access the maintenance support device 400 and generate work result information (ACT101). Specifically, the processor 404 generates the work result information including predetermined information in response to an instruction input by the call center worker via his or her terminal device. The predetermined information includes a device ID of the image forming device 100 being used by the user, a work report number, the name of the call center worker, the date of the call, a failure or an error reported by the user, an error code displayed by the user's image forming device 100 (if applicable), and a user explanation of the problem/failure provided by the user. The predetermined information or portions thereof may be automatically generated by the processor 404 or may be manually input by the call center worker via the terminal device. The processor 404 records the generated work result information in the storage device 403.

Once the maintenance work has been assigned to a maintenance worker, the maintenance worker operates his or her terminal device 300 to acquire the generated work result information. Specifically, upon receipt of an input operation by the maintenance worker via the input device 305 of the terminal device 300, the processor 304 of the terminal device 300 controls the external interface 301 to transmit a work result information request to the maintenance support device 400 (ACT102). The work result information request includes the work report number of the work result information, which corresponds to the maintenance work that has been assigned to the maintenance worker.

Upon receipt of the work result information request, the processor 404 acquires the work result information (ACT103). Specifically, the processor 404 acquires the work report number included in the work result information request, and then acquires the work result information associated with the work report number from the storage device 403. The processor 404 controls the external interface 401 to transmit a work result information response including the acquired work result information to the terminal device 300 (ACT104).

Upon receipt of the work result information response, the processor 304 controls the output unit 306 to output the work result information (ACT105). Specifically, the processor 304 records the name of the maintenance worker and the current date of work in the work result information. For example, the processor 304 may retrieve the name of the maintenance worker and the current date of work from system information stored in the terminal device 300. The name of the maintenance information may be input by the maintenance worker through the input unit 305. The processor 304 controls the output unit 306 to output the work result information including the name of the maintenance worker and the current date of work.

After the maintenance work has been done, the processor 304 accepts inputs of work results by the maintenance worker via the input unit 305 (ACT106). Specifically, the processor 304 receives inputs of information indicating whether the failure is solved, its solution, and the large, middle, and small categories of the solution, through the input unit 305. The processor 304 records the input values in the work result information. The processor 304 controls the external interface 301 to transmit the work result information to the maintenance support device 400 (ACT107).

The processor 404 records the received work result information in the storage device 403 (ACT108). Specifically, the processor 404 updates the existing work result information with the received work result information. The processor 404 generates work information on the basis of the updated work result information (ACT109). If the work information table as shown in FIG. 7 has been generated, the processor 404 adds a new record to store the received work result information. Specifically, the processor 404 acquires the date of work, the name of the maintenance worker, the device ID, the failure, the error code, whether the failure has been solved, the solution, the large category, the middle category, and the small category, from the received work result information. Next, the processor 404 specifies a device type associated with the device ID based on, for example, information stored in the storage device 403. The processor 404 generates the work information table or a new record for the table indicating the date of work, the name of the maintenance worker, the device ID, the device type, the failure, the error code, whether the failure has been solved, the solution, the large category, the middle category, and the small category. The processor 404 records the generated work information table or record in the storage device 403 (ACT110).

FIG. 9 is a flowchart of a process of tracking whether the reported failure or error has been actually solved by the maintenance work. This process is performed to identify work result information that shows a solution that has actually solved a failure. The process in FIG. 9 can be executed on a regular basis, e.g., once a day, once a week, or the like.

Initially, the processor 404 of the maintenance support device 400 acquires work result information stored in the work information table (ACT201). Specifically, the processor 404 acquires the work result information that has been stored through the process described with reference to FIG. 8 .

The processor 404 determines whether a reported failure has been solved through a maintenance work indicated in the acquired work information (ACT202). Specifically, the processor 404 determines that the failure has been solved when there is no other work result information, which indicates the same failure (e.g., a matching failure and/or the same error code) on the same image forming apparatus (e.g., the same device ID) within a predetermined period after the date of work indicated by the work information acquired in ACT201. For example, the predetermined period is seven or fourteen days. The predetermined period may be set independently for each failure or error code. For example, when the failure is a “defective image”, the predetermined period may be fourteen days after the date of work indicated by the work information acquired in ACT201. For example, when the failure is “display of error”, the predetermined period may be seven days after the date of work indicated by the work information acquired in ACT201.

When it is determined that the failure of the image forming device 100 has been solved (ACT202: YES), the processor 404 terminates the process. When it is determined that the failure of the image forming device 100 has not been solved (ACT202: NO), the processor 404 performs a restoration failure process (ACT203). Specifically, in the restoration failure process, the processor 404 sets a negative value or a negative flag indicating that the failure of the image forming device 100 has not been solved to the work result information acquired in ACT202. The processor 404 records the updated work result information in the storage device 403.

In addition, the processor 404 may control the output unit 406 to output a screen to input a reason why the failure has not been solved, e.g., “insufficient solution”, “additional solution performed”, or the like. This screen may be displayed on the output unit 406 of the maintenance support device 400 or on the output device 306 of the terminal device 300 operated by the maintenance worker who has performed the solution. The processor 404 records the input information in association with the work result information in the storage device 403. The processor 404 then controls the external interface 401 to transmit a request for reviewing the input information to a terminal used by a supervisor of the maintenance worker.

An example of the process will be described using the work information table shown in FIG. 7 . Here, the predetermined period is seven days after the date of work.

Initially, the processor 404 acquires work result information having the work report number, “REP-0004” (hereinafter called the target work result information). The processor 404 then determines whether the failure of the image forming device 100 has been solved through the maintenance work related to the target work result information. Specifically, the processor 404 searches for other work result information (e.g., other records in the work information table shown in FIG. 7 ) indicating the same device ID, the same error code, and the date of work within seven days after the date of work of the target work result information. Here, The processor 404 finds the work information indicating “REP-0005.” Therefore, the processor 404 determines that the failure of the image forming device 100 has not been solved through the maintenance work associated with the target work result information. The processor 404 performs the restoration failure process on the target work information having the work report number, “REP-0004”.

FIG. 10 is a flowchart of a process of generating information to be added to an existing manual based on stored work result information. The process in FIG. 10 is executed on a regular basis, e.g., once a day, once a week, or the like, for each type of image forming device.

Initially, the processor 404 of the maintenance support device 400 retrieves from the storage device 403 data of a maintenance manual for an image forming device 100 that is of a certain device type (ACT301). The manual data is provided by the manufacturer of the image forming device 100 and shows solutions to various failures that may occur in the image forming device 100. For example, each solution is provided for each failure or error code and shows a maintenance work to be performed, an estimate of time required for the maintenance work, and an estimate of costs of the maintenance work.

Next, the processor 404 retrieves from the storage device 403 work result information associated with the device type and indicating that the failure have been solved (ACT302). The processor 404 then compares the solution indicated by the retrieved work result information with the one indicated by the manual data to solve the same failure (ACT303), and determines whether the former is better than the latter (ACT304). To determine a better solution, the processor 404 may use the following policies:

1. The solution including more description is better;

2. The solution that can be done within less time is better; and/or

3. The solution that can be done at less cost is better.

The policies are not limited to the above-described examples. For example, a solution provided by a specific maintenance worker whose skill level is greater than some predetermined level may be considered to be better than other solutions. Additionally, the processor 404 can perform natural language analysis on the descriptions of the retrieved work result information and the manual data and determines a better description accordingly.

When determining that the solution indicated by the retrieved work result information is better than the one indicated by the manual data (ACT304: YES), the processor 404 generates additional information that indicates the solution, the large category, the middle category, and the small category shown in the work result information (ACT305), and stores in the storage device 304 the additional information in association with the corresponding solution of the manual data. For example, the additional information is embedded in the manual data and is shown together with the original solution of the manual data when referred to by a maintenance worker.

In ACT303, if there has been already additional information generated, the processor 404 may compare the solution indicated in the work result information retrieved in ACT302 and the solution indicated in the existing additional information, and determine which solution is better. In such a case, the processor 404 generates new additional information when the solution indicated in the retrieved work result information is better. Alternatively, the processor 404 may generate new additional information regardless of whether the additional information has been generated. In such a case, the processor 404 generates new additional information every time the processor 404 determines that the solution indicated in the acquired work result information is better than the one indicated in the manual data.

Additionally, the processor 404 may control the output unit 406 to output the additional information so that an operator can review the solution and merge it into the manual data.

In the maintenance system 1 configured in the above-described manner, the maintenance support device 400 records support information, such as work result information, indicating the details of maintenance work performed by a maintenance worker in the storage device 403. The support information indicates whether a failure that occurred in an image forming device 100 used by a user has been solved. The support information can be referred to by other maintenance workers. In the maintenance system 1, such support information recorded in the storage device 403 is transmitted to the terminal device 300 in accordance with a request transmitted by the terminal device 300 used by a maintenance worker. By referring to the support information, the maintenance worker can more appropriately perform his or her maintenance work on the image forming device 100.

In addition, when the same failure has re-occurred within some predetermined period after the maintenance work was performed, the maintenance support device 400 determines that the failure of the image forming device has not been fully solved and updates the corresponding support information. Thus, maintenance workers can access useful support information indicating which maintenance work has been done that has successfully and lastingly solved a failure.

Furthermore, the maintenance support device 400 can generate information that can be added to existing manual data. The information can be generated based on the support information indicating that a better solution than the existing manual solution has actually been provided by a maintenance worker. Thus, other maintenance workers can learn of such a better solution when they access the existing manual.

Modification Example

In the above-described embodiments, the processor 404 determines a manual section satisfying a predetermined condition as a change target, but is not limited thereto. For example, the processor 404 may accept an instruction from an operator through the input unit 405 to change or update the manual.

The above-described maintenance system 1 may be configured to transmit the generated additional information to a terminal used by a user of the image forming device 100. For example, when the generated additional information is stored in the storage device 403, the processor 404 may control the external interface 401 to transmit the generated additional information to a destination address registered in advance. Any notification method may be used. For example, a maintenance worker may explain the contents of the generated additional information to the user of the image forming device 100 by telephone or in person.

The maintenance support device 400 may be implemented by a plurality of information processing devices communicatively connected to each other through a network. In such a case, the components of the maintenance support device 400 may be dispersed in the plurality of information processing devices. For example, the storage device 403 and the processor 404 may be installed in different ones of the information processing devices.

The processes described in the above-described embodiments may be performed by a processor or a dedicated hardware such as an LSI.
